Bigger Chinese diesel heater?

As said insulated trunking makes a real difference, also any fittings/adaptors need to be smoothly angled and not just plain old Tees etc, ie streamlined.
I have an outlet approx 6/7 feet from the cdh 5kw and it melted the outlet, obviously thats because its crap quality plastic, but still shows the heat made it that far.
I have one t piece and that is also a reducer, second outlet is in front cabin which is another 8 feet away from the t piece and that is hot but nowheres near as hot as the insualted pipe run.

So all the heater ducting on the boat is now 30 years old and is just shiny silver so not insulated. If I was keeping it I'd replace the ducting

I'm not looking to have the boat past April so just need a working heater on it for the sale but would like something that keeps all the cabins warm if possible for the future owners.

I see the Chinese ones have gone up in price now too.

Well I'm not sure what I did but after dismantling the Chinese one and putting it back together it's working again.

Its got hundreds of running hours on it and it was spotless inside still no soot at all.
